The short version
- Each has a real cost: Microsoft Edge outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.; Microsoft Outlook microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.
- They diverge on capability: Microsoft Edge covers Internet Explorer mode, Microsoft Outlook covers Exchange calendar integration.

What people use each for
The jobs each tool is most often brought in to do.
Microsoft Edge
- A Windows estate with intranet applications that still require Internet Explorer, where IE mode buys years before a rewritenot Microsoft Outlook
- Microsoft 365 organisations that want browser sessions covered by Purview DLP and conditional access without a separate secure browser productnot Microsoft Outlook
- Fleets managed through Intune that need one browser configured by the same console as the rest of the desktopnot Microsoft Outlook
- Users who work with many tabs at once and want vertical tabs and automatic tab suspension without installing extensionsnot Microsoft Outlook
Microsoft Outlook
- Organisations on Exchange Online or Exchange Server where free/busy scheduling and room booking across everyone is a daily requirementnot Microsoft Edge
- Executive assistants managing someone else's calendar and mailbox through delegate access, which no IMAP client supports properlynot Microsoft Edge
- Regulated environments that need retention policies, legal hold and eDiscovery applied to mail centrally rather than per usernot Microsoft Edge
- Teams handling shared inboxes such as support or accounts, where permissions and tracking matter more than the mail client itselfnot Microsoft Edge
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Microsoft Edge
- Outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.
- It is Chromium downstream, so Manifest V3 applies exactly as it does in Chrome; full-strength blocking extensions cannot run, and Microsoft's add-ons store adds a second review process rather than a workaround.
- Almost all of its advantage is conditional on Microsoft 365 and Entra ID; a Google Workspace or AWS-centred organisation gets Chromium plus Microsoft's promotional surfaces and none of the Purview, Intune or conditional access value.
- Consumer-facing features including Copilot, the Discover pane, shopping notifications and sidebar apps default to on and reappear after feature updates, so suppressing them requires a maintained policy set rather than a one-off configuration.
- IE mode is a bridge with a maintenance owner attached: the Enterprise Mode Site List must be curated by somebody, and MSHTML receives security fixes but no new capability, so an application parked there gains nothing and its eventual rewrite is only deferred.
- By default browsing data feeds Microsoft services for Copilot, Discover and shopping features, which in a regulated environment turns the deployment into a policy exercise before it can be approved.
Microsoft Outlook
- Microsoft is replacing the classic Win32 client with the new web-based Outlook, and the new one runs only web add-ins, not COM add-ins, so any line-of-business integration for CRM, dictation, document management or telephony must be rewritten or the desktop stays on classic until its support window closes.
- The new client's handling of non-Microsoft accounts synchronises mail through Microsoft's cloud rather than connecting from the machine to the provider, which several organisations' data residency and handling policies do not allow, and it is not an optional behaviour.
- PST and OST files are a single-file, corruptible and effectively unshareable store, and the new client's reduced PST support means years of personal archives sitting in those files need an explicit migration plan rather than carrying forward.
- Large mailboxes turn software problems into administration ones: search index rebuilds, OST files of tens of gigabytes and the mailbox quotas of whichever plan was bought, and the usual fix is archiving policy rather than anything a user can do.
- Against IMAP or Gmail you lose most of what justifies it, including free/busy lookup, room booking, delegate access, and retention and compliance policies, because those are Exchange server features rather than client features.
- The five or six products sharing the Outlook name have materially different feature sets, so internal documentation, training and support procedures must be written per platform and a user moving between desktop, web and mobile finds the same task done differently in each.

Answered from the vendors’ own pages
Microsoft Edge: Can I uninstall Edge from Windows?
In the European Economic Area, yes, because the Digital Markets Act requires it. Elsewhere you cannot, and several Windows components will continue to open it regardless of your default browser.
Microsoft Outlook: What is the difference between classic Outlook and the new Outlook for Windows?
Classic is the long-standing Win32 application shipped with Microsoft 365 and Office LTSC. The new Outlook is a web-based client that replaced Windows Mail and Calendar. The most consequential difference is add-ins: the new client supports only web add-ins, not COM add-ins.
Microsoft Edge: How long will Internet Explorer mode be supported?
Microsoft has committed to supporting IE mode in Edge through at least 2029. It is a migration window rather than a permanent home, since the underlying MSHTML engine gets security fixes but no new capability.
Microsoft Outlook: How long will classic Outlook be supported?
Microsoft has stated support through at least 2029. That is a planning window rather than a reprieve, and organisations with COM add-in dependencies should be scoping the replacement work now.
Microsoft Edge: Do Chrome extensions work?
Yes. Edge installs extensions from the Chrome Web Store as well as its own store. Manifest V3 restrictions apply identically, so extensions that Chrome no longer supports do not work here either.
Microsoft Outlook: Can I use Outlook with Gmail or another IMAP provider?
Yes, but with reduced capability. You lose free/busy lookup, room booking, delegate access and server-side compliance policies, because those come from Exchange rather than from the client.
Microsoft Edge: Is it worth deploying if we are not a Microsoft 365 organisation?
Usually not for the management features, which depend on Entra ID, Intune and Purview. Without that stack it is Chromium with a different interface and additional Microsoft promotion.
Microsoft Outlook: Is Outlook free?
Outlook on the web and the mobile apps are free with a Microsoft account, and the new Outlook for Windows is included with Windows 11. The classic desktop application requires a Microsoft 365 subscription or an Office perpetual licence.
Microsoft Edge: Does it run on Linux?
Yes, there are official Linux builds. Some Windows-specific features, including IE mode, are not available there.
Microsoft Outlook: Will my COM add-ins work in the new Outlook?
No. The new client supports only the cross-platform web add-in model. Vendors must publish a web add-in, and where they have not, the choice is to stay on classic Outlook or replace the integration.
